How to select materials for laminar flow operating room purification project? The characteristics of clean operation Department are core project, image project and semi permanent infrastructure project. Therefore, the selection of materials must be based on these three points, at least to ensure the service life of more than 10 years, and combined with the functional requirements to achieve the best cost performance of materials.
How to select materials for laminar flow operating room purification project? The characteristics of clean operation Department are core project, image project and semi permanent infrastructure project. Therefore, the selection of materials must be based on these three points, at least to ensure more than 10 years of service life, and combined with the functional requirements to achieve better cost performance of materials.
The material selection of laminar flow operating room purification engineering is as follows:
One. Wall and ceiling materials
Clean operating room and clean corridor (including dressing room) are the key parts of the whole clean operating department. Their decorative materials should be superior to other parts, and meet the requirements of beauty, rust prevention, corrosion prevention, scrub resistance, easy cleaning, dust-free and durable. Their installation structure should also meet the characteristics of the operating room. The surface material of the ceiling is less likely to be damaged, so it can be one level lower than the wall material.
2。 Wall and ceiling materials of clean auxiliary room, clean corridor and clean area
Because the clean auxiliary room, clean corridor and clean area auxiliary room are relatively minor parts of the clean operating department compared with the clean operating room and clean corridor, and the area is often larger. In order to reduce costs, wall and ceiling materials can be one level lower than those of operating rooms and clean corridors.
Three. Ground materials of operation Department
对于功能要求，手术室的地板材料必须满足防变色、防静电、耐磨、吸音的特点，所以橡胶地板材料是首 选。由于运营部其他走廊及辅助用房人 流较大，对地板材料的突出要求是耐磨。为了降低成本，我们可以选择比橡胶材料更差的PVC均质材料。
For functional requirements, the floor material of operating room must meet the characteristics of anti color, anti-static, wear-resistant and sound-absorbing, so rubber floor material is the first choice. Due to the large flow of people in other corridors and auxiliary rooms of the operation Department, the outstanding requirement for floor materials is wear resistance. In order to reduce the cost, we can choose PVC homogeneous material which is worse than rubber material.
Four. Purified air treatment unit
To determine the quality of the purified air treatment unit, the following are the key points:
A. Is it a sanitary device? Because the detection index of health unit is higher than that of common unit, its structure is more in line with the concept of purification;
B. The performance of the fan must pass the inspection of the authority and have corresponding marks to ensure the performance;
C. The lower the air leakage rate, the better the anti condensation performance (test report shall be provided), and the better the unit performance;
D. Under the same technical conditions, the lower the noise, the better;
E. Appearance design and manufacturing process;
5. Laminar centralized air supply device
The laminar flow centralized air supply device is located at the end of the purification air supply system of the operating room, which is the clean part of the whole purification system. The quality of this part has a great influence on the air cleanliness index of the purification system, which needs special attention.
6。 High efficiency filter
The performance of the high efficiency filter depends on two factors
A. The filtration efficiency of 0-3 μ m dust particles depends on the quality of filter paper;
B、 是否逐一检查泄漏，高 效过滤器非常精致。有大针孔的针孔会使它无用。因此，如果不逐一检查泄漏情况，其性能就无法保证。
B. Whether to check the leakage one by one, the high efficiency filter is very delicate. A pinhole with a large pinhole will make it useless. Therefore, if the leakage is not checked one by one, its performance cannot be guaranteed.
